Abstract Photoelectrocatalysis has the capability to utilize solar energy produce hydrogen and valuable chemicals; however, their conversion efficiency remains reach practical thresholds. Here, a rapid‐ramping annealing strategy is reported synthesize nanoporous Mo‐doped bismuth vanadate (MBVO) photoanodes with (001)‐preferred orientation. This approach leverages enhanced carrier transport along crystallographic [001] direction, optimizing bulk photoelectrical properties of MBVO photoanodes. By substituting surface oxygen evolution reaction glycerol oxidation reaction, photoconversion significantly boosted, reaching photocurrent density 7.45 mA cm −2 at 1.23 V versus RHE an incident photon‐to‐current ≈100% for generation, accompanied by production value‐added products in high rate (≈1700 mmol m h −1 total) total Faradaic up 96%. These results shed light on construction photoelectrocatalysis systems demonstrating potential bulk‐phase engineering coupled design.

Interfacial photoelectrochemistry at photoanodes has been extensively researched for solar energy conversion, but its application the production of high-value-added chemical compounds in organic chemistry still presents challenges. Herein, we report photoelectrocatalytic Cl-mediated C(sp3)–H aminomethylation alkanes with self-developed and reusable BiVO4 photoanodes. The swift condensation aniline aldehydes, along decrease electricity input by photogenerated holes photoanodes, work together to prevent excessive oxidation aniline, leading high yields desired product. Mechanistic experiments demonstrate that Cl- ions, as key mediators, could be attracted oxidized form Cl2. This is followed light-promoted homolytic cleavage Cl2, generating Cl radicals efficiently abstract hydrogen atoms from hydrocarbons. opens an avenue interfacial photoelectrochemical synthesis demonstrates a potential method optimizing conversion into fuels. A stable recyclable photoelectrode material was developed efficient hydrocarbons cell, which provides promising fuel conversion.
